[0046] 5 g of ZSD-2 was dissolved in 50 ml of DCM, and 1.77 ml of phenylhydrazine and 220 mg of DMAP were added in an ice bath, then 3.72 g of DCC was added in batches and left at room temperature overnight. After the completion of the reaction, suction filtration was performed and the mother liquor was concentrated and then extracted with EA, washed with saturated NaCl solution, and dried with anhydrous sodium sulfate. Finally, recrystallization was performed to obtain 5.7 g of ZSD-14 product. 250 mg of ZSD-14 was dissolved in 3 ml of DCM, 1 ml of trifluoroacetic acid was added, and the reaction was complete after stirring at room temperature for 30 minutes. After the reaction, the solvent was evaporated to dryness to obtain ZSD-16 for later use. ZSD-16 was dissolved in toluene, 0.3 ml of triethylamine and 104 mg of p-hydroxybenzaldehyde were added in order, and then refluxed at 110° C. for 1 hour. The mixture was extracted with EA, washed with saturated NaHCO.sub.3 and NaCl solutions, and dried with anhydrous sodium sulfate. After the completion of the drying, the solvent was concentrated and further separated and purified by column chromatography to obtain 161 mg of the target product of ZSD-20.
